Adjustable-head cleaning implement

ABSTRACT

An adjustable cleaning head for a cleaning implement. The cleaning head has first and second cleaning panels defining respective first and second working surfaces. The first cleaning panel is pivotably attached to the second cleaning panel, whereby the first cleaning panel is movable relative to the second cleaning panel. The position of the first cleaning panel relative to the second cleaning panel is fixable, such that the first and second working surfaces form a fixed cleaning angle therebetween. The cleaning angle is greater than 180 degrees and less than 270 degrees.

TECHNICAL FIELD AND BACKGROUND OF THE INVENTION

This invention relates to an improved cleaning implement, an adjustable head for a cleaning implement, and a method for cleaning a floor surface area. The invention is especially applicable for use in combination with disposable wet and dry cloths applicable for mopping and dusting floors, respectively.

Existing commercial products, such as the electrostatic cloth marketed under the brands Swiffer® and Grab-it®, represent a substantial improvement over the standard broom in removing dust, dirt, hair, and other loose debris from floors. For the most part, sweeping using a standard broom simply stirs up matter that ultimately resettles on the floor only after the job is believed to be finished. While the existing products do a moderately effective job of trapping dust particles before they have a chance to escape, the real problem lies in the limited design of the cleaning head used to carry the cloth. Because these implements utilize an entirely flat cleaning head, when the head and attached cloth are moved across the floor, all of the dust collects only at portions of the cloth covering the front and/or rear edge of the head. Consequently, the cleaning head operates much like a snowplow with substantially all the loose debris piling up and accumulating at the leading edge. This debris is generally pushed around the room, and engages only a very small portion of the cleaning cloth. The vast majority of the cloth is not utilized.

In recognizing this problem, one existing product advertizes that its dry cloths are extra-thick with “unique, V-shaped ridges that pick up more dirt, dust, and hair than traditional methods.” Notwithstanding this modification/improvement, because the cleaning head remains entirely flat, the loose debris continues to be pushed around and not collected over a vast majority of the cloth surface area. As a result, a long felt need exists for an improved head design which enables proper utilization of the entire cloth, and which more effectively captures and removes dirt, dust, hair, and other debris from the floor with less work.

SUMMARY OF INVENTION

Therefore, it is an object of the invention to provide an adjustable cleaning head for an improved cleaning implement.

It is another object of the invention to provide a cleaning head which includes independently adjustable cleaning panels that work together to utilize the entire cleaning cloth, and thereby capture and remove a maximum amount of dust, dirt and debris from the floor.

It is another object of the invention to provide a cleaning head which is conveniently adjustable between multiple configurations.

It is another object of the invention to provide a cleaning head which avoids “snowplowing” loose debris and wet spills across the floor.

It is another object of the invention to provide a cleaning head which defines a debris entry and collection zone between the floor and a raised cleaning panel.

It is another object of the invention to provide an improved method for cleaning a floor.

These and other objects of the present invention are achieved in the preferred embodiments disclosed below by providing an adjustable cleaning head for a cleaning implement. The cleaning head has first and second cleaning panels defining respective first and second working surfaces. The working surfaces are preferably generally planar. Means are provided for pivotably attaching the first cleaning panel to the second cleaning panel, whereby the first cleaning panel is movable relative to the second cleaning panel. Means are provided for fixing the position of the first cleaning panel relative to the second cleaning panel, such that the first and second working surfaces form a fixed cleaning angle therebetween. The cleaning angle is greater than 180 degrees and less than 270 degrees. Preferably, the cleaning angle is approximately 210 degrees.

According to another preferred embodiment, the means for pivotably attaching the first and second cleaning panels is a living hinge.

According to another preferred embodiment, the means for fixing the position of the first cleaning panel includes first and second interfering elements cooperating to frictionally lock the first cleaning panel in position relative to the second cleaning panel.

According to another preferred embodiment, a third cleaning panel is attached to the second cleaning panel, and defining a third generally planar working surface. Alternatively, the third working surface may be upwardly curved.

According to another preferred embodiment, means are provided for pivotably attaching the third cleaning panel to the second cleaning panel.

According to another preferred embodiment, means are provided for fixing the position of the third cleaning panel relative to the second cleaning panel, such that the third and second working surfaces form a fixed cleaning angle therebetween.

According to another preferred embodiment, the fixed cleaning angle between the third and second working surfaces is greater than 180 degrees and less than 270 degrees.

In another embodiment, the invention comprises an upwardly-angled cleaning head for a cleaning implement. The cleaning head has first and second cleaning panels defining respective first and second working surfaces. The working surfaces form a fixed cleaning angle therebetween. The cleaning angle is greater than 180 degrees and less than 270 degrees. The first and second cleaning panels may be separately formed, or integrally-formed together (e.g., molded) as a single unit. The working surface of the first cleaning panel may extend at a distinct angle, or may be upwardly curved. In the case of an upwardly-curved working surface, the cleaning angle is measured relative to a notional tangent extending from an adjacent edge of the working surface of the second cleaning panel and touching the curved working surface of the first panel at a point without intersecting the point.

In another embodiment, the invention comprises a method for cleaning a surface area. The method includes the steps of upwardly tilting a first cleaning panel relative to a second cleaning panel of an adjustable cleaning head. The first and second cleaning panels define respective first and second working surfaces. The working surfaces are preferably generally planar. The position of the first cleaning panel relative to the second cleaning panel is then locked, such that the first and second working surfaces form a fixed cleaning angle therebetween. The cleaning angle is greater than 180 degrees and less than 270 degrees. Using the handle, the adjustable cleaning head is then pushed over the surface area to be cleaned.

DESCRIPTION OF PREFERRED EMBODIMENT AND BEST MODE

Referring now specifically to the drawings, an improved cleaning implement according to the present invention is illustrated in FIG. 1, and shown generally at reference numeral 10. The cleaning implement 10 includes an elongated handle 11, an adjustable cleaning head 12, and a conventional joint 14 interconnecting the handle 11 and head 12. The joint 14 enables pivoting and swivel movement of the cleaning head 12 relative to the handle 11.

The cleaning head 12 comprises multiple pivotably-attached cleaning panels 15, 16, and 17. The cleaning panels 15, 16, 17 are preferably joined together by respective longitudinal living hinges 18, 19, such that outside panels 15 and 17 are independently adjustable relative to the center panel 16. Preferably, the joint 14 interconnecting the handle 11 and cleaning head 12 is formed with a top of the center panel 16. Each of the cleaning panels 15, 16, 17 defines a generally planar working surface 15A, 16A, and 17A which cooperates with a disposable wet or dry cloth 20 to clean a floor surface area, such as wood, vinyl, tile, or other flooring material. Cloth holders 21, 22, 23, and 24 are located on top sides of the cleaning panels 15 and 17, and are designed to receive and hold respective corners of the disposable cloth 20. The disposable wet cloths, such as those marketed under the Swiffer® Brand, are preferably pre-soaked with an advanced cleaning solution that dissolves stains and dries quickly.

The position of each outer cleaning panel 15, 17 is releasably fixable relative to the center panel 16 using any suitable means. For example, in the embodiment shown, the cleaning panels 15, 16, 17 comprise overlapping, upstanding, lateral tabs 26, 27, and 28. The outer panel tabs 26 and 28 have respective detents 31 which, upon upward pivoting movement of the outer panels 15, 17, are designed to selectively mate with complementary indents 32 (or holes) formed with the center panel tab 27. Once mated, as shown in FIG. 4, the detent 31 and mouth of the indent 32 cooperate to frictionally retain the outer panel 15, 17 in the desired selected position during use of the cleaning implement 10. Other interfering structure, such as spring-loaded pins, cotter pins, clips, ties, screws, or the like, may be used instead of, or in addition to, the above to further set the position of the outer panels 15, 17 relative to the center panel 16.

Finger posts 33 and 34 extending from each outer panel tabs 26, 28 are adapted for being engaged by the user to move the outer cleaning panels 15, 17 between the various positions shown in FIGS. 3A, 3B, 3C, and 3D. In FIGS. 1 and 3A, the two outer cleaning panels 15, 17 are positioned generally coplanar to the center cleaning panel 16. In this position, the cleaning head 12 is especially applicable for wet mopping, as each of the working surfaces 15A, 16A, 17A engages the wet cloth (not shown) to clean the floor surface area “F”. The cleaning angles (α) and (β) formed between the first working surface 15A and center working surface 16A, and between the second working surface 17A and center working surface 16A, respectively, are each substantially 180 degrees.

In FIGS. 2 and 3B, both outer cleaning panels 15, 17 are raised to dry clean the floor surface area using a disposable electrostatic dusting cloth (not shown). In this position, the cleaning angles (α) and (β) between the first working surface 15A and center working surface 16A, and between the second working surface 17A and center working surface 16A, respectively, are each substantially 210 degrees. As the cleaning head 12 is moved back and forth over the floor surface area “F”, dust, dirt, hair, and other dry loose matter is captured beneath the raised outer panels 15, 17 and collected on the dry cloth adjacent the working surfaces 15A, 16A, and 17A. Consequently, the cleaning panels 15, 16, and 17 and respective working surfaces 15A, 16A, and 17A work together to utilize the entire cloth, and thereby capture and remove a maximum amount of dust, dirt and debris from the floor surface area “F”. The joint 14 interconnecting the handle 11 and head 12 allows the user to conveniently reverse the leading and trailing cleaning panels 15, 17, such that the entire cloth may be more effectively utilized prior to disposal. The resulting spaces formed between the floor “F” and working surfaces 15A and 17A define respective debris entry and collection zones “Z”. Larger dust and dirt particles are captured by the cloth adjacent the raised surfaces 15A and 17A, while the finer particles pass beneath the center panel 16 and are captured by the cloth adjacent the working surface 16A. This head configuration is also applicable for mopping to pick-up wet spills, such as jelly and syrup.

FIGS. 3C and 3D illustrate further configurations of the adjustable cleaning head 12. In FIG. 3C, the outer cleaning panel 15 is raised while the outer panel 17 is positioned generally coplanar to the center panel 16. In this position, the cleaning angle (α) between the first working surface 15A and center working surface 16A is substantially 210 degrees. The resulting space formed between the floor “F” and working surfaces 15A defines a debris entry and collection zone “Z”, as previously described. The cleaning angle (β) between the second working surface 17A and center working surface 16A is substantially 180 degrees. In FIG. 3D, the outer cleaning panel 17 is raised while the outer panel 15 is positioned generally coplanar to the center panel 16. In this position, the cleaning angle (β) between the second working surface 17A and center working surface 16A is substantially 210 degrees. The resulting space formed between the floor “F” and working surface 17A defines a debris entry and collection zone “Z”. The cleaning angle (α) between the first working surface 15A and center working surface 16A is substantially 180 degrees.

In alternative embodiments (not shown), the adjustable head may include only two cleaning panels pivotably connected together by living hinge or suitable hardware. The head may also be integrally molded such that one or both outer cleaning panels are permanently titled. In this embodiment, the working surfaces define respective permanent cleaning angles each greater than 180 degrees and less than 270 degrees, as previously described.
